# Conversion Calculator vs Unit Ease

The clearest difference is rating: Unit Ease at 5.0 against Conversion Calculator's 4.8. Unit Ease also leads on iOS requirement (13.0 vs 17.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. Conversion Calculator sells 1 one-off in-app purchase and Unit Ease sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Unit Ease holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 165 and 67 respectively. Written reviews complicate that: 100% of Conversion Calculator's written reviews are positive against 95% of Unit Ease's, so the app with the better star average is not the one people write more warmly about.

Conversion Calculator ships an update every 5 weeks, Unit Ease every 4 weeks. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
